The Boring of Scientific Research

Zhang Ming on the side calmly manipulated the TENSOR-II research-grade Fourier transform infrared spectrometer in his hand, and the spectrum on it was analyzing the changes in the materials in front of him.

“Continue heating.”

Zhang Ming said to Zhou Sen who was operating at the side, and the curve on the spectrometer beside him was constantly fluctuating.

Zheng Sen next to him was in charge of adding some catalysts to the materials in front of him and recording some experimental data.

The three of them worked together, and soon, the graphene in front of them was coated on the silver sheet.

“Check the effect of this graphene silver plating.”

Zhou Ming said to Zhang Ming who was on the side.

Zhang Ming nodded, and carefully picked up the graphene-coated silver sheet with tweezers, and placed it on the glass slide aside.

Started to continue the experiment.

Soon, the physical properties of the graphene-coated silver sheet were detected, and everyone frowned and shook their heads.

“Clean up, and continue with the second experiment later!”

Zhou Ming said to Zhang Ming and Zheng Sen who were beside him.

Several people stopped, and Zhang Ming and Zheng Sen checked the experimental data and instruments, while Zhou Ming looked at Cheng Hao, who was observing curiously, and said with a smile: “How is it? Do you think it is very difficult to do the experiment?” boring?”

Cheng Hao pondered for a while, then shook his head towards Zhou Ming in front of him.

“I think it’s okay. After all, the repeated experiment is actually just to find a better possibility. I’m just curious. How did our laboratory get its funding?”

Cheng Hao looked at Zhou Ming in front of him curiously and asked.

“We are the laboratory of academicians.”

Zhou Ming paused, looked at Cheng Hao in front of him and said with a smile: “Our laboratory is not short of funds, not only from the state, but also from state-owned enterprises that send a lot of funds to our laboratory every year. So, Our laboratory is not short of funds!”

Hearing Zhou Ming’s words, Cheng Hao nodded thoughtfully. At this moment, he suddenly thought of something, and curiously asked Zhou Ming who was beside him: “By the way, who owns the products produced by our laboratory? ? Or corporate?”

“It depends.”

Zhou Ming paused.

“Generally speaking, the intellectual property rights of our laboratory are shared by three parties. Part of the laboratory, part of the country, and part of the funded enterprise.”

“Oh!”

Cheng Hao nodded.

At this time, Zhou Ming looked at Cheng Hao with a hint of emotion in his eyes, and said, “In fact, doing our kind of experiment is more about physical work, especially this new material. Although we know its physical properties, But I don’t know much about its properties with other materials, and I don’t quite understand the effect it produces when it is mixed with other materials.

It is even more unclear what kind of combination can make this material exert the best effect, and what the best effect is, it is actually hard to say! This requires a material-by-material trial, and then what kind of sparks will these materials collide with graphene, in fact, it is similar to a lottery.

But the lottery doesn’t need to control the ingredients, we need it! ”

As he spoke, Zhou Ming smiled wryly and shook his head.

“Then senior, have you made any achievements?”

Cheng Hao looked at Zhou Ming in front of him curiously and asked.

“Yes! Why not.”

Zhou Ming smiled, looked at Cheng Hao in front of him and said.

“We started to study the composite material of polyvinyl alcohol (PVA) and graphene, and found that the physical and mechanical properties of the combination of these two materials are really good. After some experiments, we came up with a complex graphene content of 1.8. vol% polyvinyl alcohol (PVA) composite material, studied its mechanical properties, and found that the tensile strength of the composite material increased by 150%, and the Young’s modulus increased by about 10 times!”

“Ten times!”

Hearing Zhou Ming’s words, Cheng Hao’s eyes showed surprise.

“Ok!”

Zhou Ming nodded.

“This material is not bad, the three of us all got a bonus of 10,000!”

As he spoke, a smile appeared in Zhou Ming’s eyes.

“Okay! Let’s continue the experiment! Little brother, just watch from the side.”

Zhou Ming said to the three people around him.

“Oh! Good!”

Cheng Hao nodded. Of course he would not have any objections. After all, it was his first time to come to the laboratory, so he had to listen to his seniors for everything.

For a whole day, Cheng Hao spent all his time in the laboratory, watching several of his seniors constantly experimenting with different materials and graphene, whether they were coated with graphene in different proportions, or mixed.

Carry out experiments of varying degrees.

At first Cheng Hao watched it with relish, but in the end, Cheng Hao became numb.

After eating at noon, there was not much lunch break, and the experiment in the afternoon started again.

At this moment, Cheng Hao couldn’t bear it anymore, and asked Zhou Ming who was beside him: “Senior Zhou Ming, if we experiment like this,What kind of material are you looking for? Or is there no purpose? ”

“of course not!”

Zhou Ming smiled, looked at Cheng Hao and said, “The purpose of our recent experiments is to find a graphene composite material that can be used in space, and it needs to have enough tensile strength and enough Young’s Modulus, the most important thing is that the super-conductivity of graphene itself, as well as the hardness, must be taken into account, and it is best to be able to shield the strong radiation of space…”

Hear Zhou Ming’s words.

Cheng Hao: “…”

It sounds so difficult.

“Okay, stop talking! Continue to deal with it!”

All afternoon, Zhou Ming and the three were doing material experiments, which was boring.

Until the end of the afternoon.

Zhou Ming found Cheng Hao.

“Can you use matlab?”

MATLAB means matrix factory, and the software mainly faces the high-tech computing environment of scientific computing, visualization and interactive programming. It integrates many powerful functions such as numerical analysis, matrix calculation, scientific data visualization, and modeling and simulation of nonlinear dynamic systems in an easy-to-use window environment. Fields provide a comprehensive solution.

It is a very powerful app. People who do scientific research like this app very much.

Cheng Hao has used it before.

He nodded, and said to Zhou Ming in front of him, “Yes!”

Zhou Ming nodded, with a look of tiredness on his face, and said with a wry smile to Cheng Hao: “We have been doing experiments for nearly 20 days, but we still haven’t found any trace of such materials, but the 20 We still have the test data for many days, why don’t you take a look at it for us!”

“Can!”

Cheng Hao nodded and agreed.

“Zhang Ming.”

Zhou Ming called out to Zhang Ming who was on the side.

Zhang Ming took out a USB flash drive from the side, walked to Zhou Ming’s side, glanced at Cheng Hao, pondered for a while, and handed the USB flash drive in his hand to Cheng Hao.

“The data here has a certain degree of confidentiality, don’t disclose it!”

“it is good!”

After Cheng Hao took the USB flash drive, he hurriedly said to Zhang Ming.
